Sapera Acquisition Methods
Sapera acquisition methods define the control and timing of the camera and frame grabber board.
Various methods are available, grouped as:
• Camera Trigger Methods (method 1 supported)
• Line Trigger Methods (method 1)
• Line Integration Methods (method 1 through 4 supported)
• Time Integration Methods (method 1, 3, 5, 6, 8)
• Strobe Methods (method 1, 3, 4 supported)
Refer to the Sapera LT Acquisition Parameters Reference manual (OC-SAPM-APR00) for detailed
information concerning camera and acquisition control methods.
Trigger to Image Reliability
Trigger-to-image reliability incorporates all stages of image acquisition inside an integrated
controller to increase reliability and simplify error recovery. The trigger-to-image reliability model
brings together all the requirements for image acquisition to a central management unit. These
include signals to control camera timing, on-board frame buffer memory to compensate for PCI bus
latency, and comprehensive error notification. If the Xtium-CL MX4 detects a problem, the
application can take appropriate action to return to normal operation.
The Xtium-CL MX4 is designed with a robust ACU (Acquisition and Control Unit). The ACU monitors
in real-time, the acquisition state of the input plus the DTE (Data Transfer Engine) which transfers
image data from on-board memory into PC memory. In general, these management processes are
transparent to end-user applications. With the Xtium-CL MX4, applications ensure trigger-to-image
reliability by monitoring events and controlling transfer methods as described below:
